russell is now a single parent to the 3-year-old daughter she had with tamerlan. her attorney says she didn't know her husband was a bombing suspect until she saw it on television. >> we are learning more about russell's husband and growing dissatisfaction with mainstream religion. three months before the marathon bombings, tamerlan tsarnaev, visited a cambridge mosque and shouted out after the speaker compared the prophet muhammad with martin luther king jr. in his first interview, he tells abc news how the congregation reacted. >> they just straight up shouted at him that, you need to leave, you know, so he stepped out of the sermon. after the sermon and prayers were done, some of the leaders of the center sat down with him and said, listen, you have a clear choice. either you're silent from now on during the sermons or you're not going to be welcome here. >> he says that wasn't tamerlan's only outburst. another time, he loudly objected when a speaker said it was appropriate to celebrate thanksgiving the same way one would celebrate the birthday of the prophet.
